There is no Kconfig symbol PPC_WSP_COPRO. The select statement for it is
a nop. Drop it.

A short treatise on the uneventful life of PPC_WSP_COPRO in the mainline
kernel tree

Release v3.0 included commit 76b4eda866c4936af8d696f040abea56bf688e16
("powerpc: Add A2 cpu support"). It added some code wrapped in an
"#ifdef CONFIG_PPC_WSP_COPRO" and "#endif" pair. It did not add a
Kconfig symbol PPC_WSP_COPRO. Neither did it add a preprocessor #define
for CONFIG_PPC_WSP_COPRO. There haS actually never been such a symbol or
such a macro in the mainline tree.

Release v3.3 included commit fac26ad4f9cb794c9d1032f55f40a31cb55be09a
("powerpc/book3e: Add ICSWX/ACOP support to Book3e cores like A2"). It
basically renamed CONFIG_PPC_WSP_COPRO to CONFIG_PPC_ICSWX. It did not
elaborate why it did that. But at least PPC_ICSWX was a valid Kconfig

Release v3.3 also included commit
cc35b6766878e31accc95c3fdae945bdadc73a46 ("powerpc/book3e: Add Chroma as
a new WSP/PowerEN platform."). That commit added a Kconfig select
statement for PPC_WSP_COPRO. It is not clear why it did that. Current
opinion is that it served no purpose and that the kernel tree would be
better of without that statement.
